ISO 4589-2 Limited Oxygen Index Tester With Paramagnetic Oxygen Sensor
Introduction:
The Limited Oxygen Index Tester is designed to determine the minimum oxygen concentration required to sustain combustion of materials under controlled conditions. Utilizing an imported paramagnetic oxygen sensor and high-precision mass flow controllers, this analyzer ensures accurate and reliable results for homogeneous solids, laminated materials, foams, films, and textiles. It is ideal for laboratories and industries focused on fire safety evaluation, compliant with ISO 4589-2, GB/T 2406-2009, and other international standards.
Key Features:
Paramagnetic Oxygen Sensor: Lifetime durability, eliminating frequent replacements.
Auto-Adjustment System: PLC touchscreen controls oxygen concentration automatically.
Gas Mixing Chamber: Ensures uniform gas distribution for precise measurements.
Dual Gas Flow Meters: ±1% accuracy for nitrogen and oxygen flow control (1.0–15.0 L/min).
Safety Compliance: Built-in automatic calibration and safety circuits.
The airflow in the combustion tube is 40mm/s±2mm/s, and the concentration adjustment accuracy is ±0.1%;
The airflow at the top of the combustion tube is 90mm±10mm/s;
The portable igniter sprays downward 16±4mm, and the flame can be adjusted in the range of 10~30mm;
The measurement time can reach 5min, and the accuracy is ±0.1s;
Dual flow meter and pressure gauge device: accuracy ±1%;
Working pressure: 0.1MPa;
The glass tube is 500mm high and the inner diameter is 80mm.
